Closes #769. Every re-embed pass clobbered code-chunk metadata (language, symbol_name, symbol_type, start_line, end_line, parent_symbol_path, doc_comment, symbol_name_qualified) to NULL, disabling code-def queries across thousands of indexed chunks. Two complementary fixes: embed.ts — three re-upsert call sites (embedPage, embedAll non-stale, embedAllStale autopilot path) build ChunkInputs from loaded chunks; they were stripping the 8 metadata fields. New preserveCodeMetadata helper threads those fields through consistently. Integrated cleanly with v0.34.4.0's cursor-paginated --stale hardening — the wrap sits inside the worker function between embedBatchWithBackoff and engine.upsertChunks. postgres-engine.ts + pglite-engine.ts — upsertChunks ON CONFLICT clause OVERWROTE metadata columns from EXCLUDED. Asymmetric vs the embedding/embedded_at columns which already used a chunk_text-gated CASE pattern (re-chunk → trust EXCLUDED, re-embed → COALESCE preserve). Applied the same pattern to all 8 metadata columns. Three regression tests in test/embed.serial.test.ts cover --stale (autopilot), --all, and --slugs paths. Each loads a chunk with full metadata, runs runEmbed, and asserts engine.upsertChunks receives the metadata round-tripped. Coexists with master's D5 embedBatchWithBackoff test block. Backfill required after deploy: \`gbrain sync --strategy code --force --source <id>\` per code source to re-populate metadata via the chunker. Without backfill, existing NULL columns stay NULL — re-embed alone never produces metadata, only the chunker does. Originally landed as part of PR #768 (the wave that bundled #767 + fix; this PR carries the #769 fix alone with no scope overlap.

// parent_symbol_path, doc_comment, symbol_name_qualified) on every
|

// but embed.ts loaded chunks via getChunks then mapped them to a
|
||
// stripped ChunkInput carrying only 5 fields. upsertChunks then
|
||
// OVERWROTE (not COALESCEd) the metadata columns from EXCLUDED, so
|
||
// re-embed wiped them to NULL. End result on a real brain: 4875 code
|
||
// pages, 47866 chunks, all with NULL language/symbol_name/symbol_type;
|
||
// code-def returned 0 hits across every indexed repo.
|

//
|

// All three runEmbed paths (--stale autopilot, --all, --slugs) must
|
||
// thread metadata through the re-upsert. Tests below assert that the
|
||
// engine.upsertChunks call carries the same metadata it loaded.
